* eGroupWare API: VFS - Homedirectories
*
* This class implements some necessary stuff for user- and group-directories ontop the vfs class.
*
* Some of it is already implemented in the filemanager app, but it's also needed for the WebDAV access:
* - show only directories in /home, to which the user has at least read-access
*
* Stuff dealing with creation, renaming or deletion of users via some hooks from admin:
* - create the homedir if a new user gets created
* - rename the homedir if the user-name changes
* - delete the homedir or copy its content to an other users homedir, if a user gets deleted
* --> these hooks are registered via phpgwapi/setup/setup.inc.php and called by the admin app
